BOSTON (AP) -- President Barack Obama is in Boston, to speak at an interfaith service honoring the three people killed and 170 injured in the bombing at the Boston Marathon.
Before leaving the White House, a spokesman says, Obama received a briefing from his national security adviser on the status of the investigation into the blasts.
There's a heavy police presence around Boston's main Roman Catholic cathedral as residents lined up to mourn the victims of the marathon bombing at the interfaith service.
Streets are blocked off around the Cathedral of the Holy Cross in Boston's South End, and people have lined up since before dawn hoping to get one of the roughly 2,000 seats inside. By 9 a.m., they were being turned away.
Someone was holding a green flag bearing the words "forgiveness" and "peace."
Among the hundreds in line was 18-year-old Eli Philips. The college student was a Marathon volunteer and was wearing his volunteer jacket on Thursday morning.
He says he's still shocked that "something that was euphoric went so bad."
